Yup, same as with the Aero. Great-looking bike, should be reliable if well-maintained, but it doesn't appear to have hydraulically-adjusted valves (key question to ask when buying a bike, IMHO), looks like it has tube tires (yuck) and it uses a chain drive (I like belt or shaft-drive MUCH better).
previously-owned '95 Yamaha Virago 750
The Yamaha appears to be a direct competitor of the Kaw Vulcan 750, except that it's air-cooled (it'll overheat faster when stuck in summer traffic). Like the Kaw, the Yamaha design has been tried and true since the 1980s (1981!), so there should be no shortage of parts for it.
I neglected to mention earlier about the Kaw Vulcan 750 that it has a VERY complete instrument panel (tach AND speedo). Unlike most bikes, it also has a kickstand AND center stand -- very nice when you want to work on it.
